See the New York Times for a story and some recipes for green smoothies from Martha Rose Shulman. We agree, green smoothies are one of the best for energy. We put more greens in ours because we really like the flavor! But a little goes a long way. These are really creative ideas. I'm looking forward to making the one with cumin and cucumber, reminiscent of an Indian lassi.http://well.blogs.nytimes.com/2014/05/02/drink-your-greens/?action=click&contentCollection=Europe&module=MostEmailed&version=Full&region=Marginalia&src=me&pg
